Orientation of gramine and hordenine within the PLPC bilayer. Distribution of angles (A) between the PLPC bilayer normal and vectors defined on each alkaloid as shown in the insets and (B) between the PLPC bilayer normal and vectors orthogonal to the surface defined on each alkaloid by 3 points of the cyclic part (insets of B: schematic representation of the hordenine (left) and gramine (right) orientation within the lipid bilayer). Blue line: gramine, red line: hordenine.
